摘要
在野外调查中发现，毛华菊（Ｄｅｎｄｒａｎｔｈｅｍａｖｅｓｔｉｔｕｍ）的花朵存在丰富的变异，而且这些变异形态和栽培菊花（Ｄ．×ｇｒａｎｄｉｆｌｏｒｕｍ）的花形变化极为相似．该文参照栽培菊花花形的分类，对这些变异类型进行了整理．同时，也对毛华菊花朵变异的原因进行了初步的探讨．
Dendranthema vestitum is one of the ancestors of D. grandiflora. Many bloom forms of D. vestitum are first found in Anhui and Henan provinces and such flower variations are much similar to that of D. grandiflora. In the paper, these flower forms are classified according to the typical characteristics such as ligule form, ligule number, flower size and color that are practically used in the classification systems of D. grandiflora. Moreover, the reasons of the phenomenon are also reported preliminarily.\=
